// about
Hi, I'm Jim Tobin.
I'm a CCIE-level network, cloud and security engineer. For 20+ years I've designed, built and run the infrastructure that businesses depend on — from the service-provider edge to the enterprise data centre.
These days that means routing and switching, SD-WAN and SASE, segmentation and security — and increasingly the AI-powered web apps and internal tools that sit on top. I also co-founded UNSX Core, an engineering firm covering the same ground at team scale.
I take on day-rate contract work and selective build projects. If you've got something that has to be designed properly and actually hold up in production, that's the work I like.
